Overview

A boat owner replacing weathered speakers gets a coaxial pair here, with a polypropylene woofer and a built in crossover feeding the silk tweeter. The grilles and mounting hardware come in the box, and the speaker has more than one hole pattern.

Marine certification and a water resistant build are the reasons to choose them, and car use still works through the same coaxial layout. The listing gives no cutout depth or screw pattern, so measure the opening before ordering.

Who it's for

Boaters and owners of ATVs, motorcycles or cars who need a weather tolerant coaxial pair. Anyone with a different opening size, or wanting separate drivers, should look elsewhere.

Pros and cons

Pros
  • Hardware and grilles included
  • Fits more than one hole size
  • Silk dome tweeter with crossover
Cons
  • Mounting depth not listed
  • Sensitivity not given
  • Water resistant, not fully submersible

Performance notes

The polypropylene cone resists moisture, and laser imaging in the Dynamic Balance design is meant to reduce cone resonance. The built in crossover sends highs to the tweeter, so the speaker plays full range from one pair of wires.
